Why isn't there any repulsive force between Na+ and K+ disrupting thier roles in transmembrane voltage/ action potentials Please forgive my elementary knowledge :) A good habit to source answers nonetheless, thanks! |

Why isn't there any repulsive force between Na+ and K+ disrupting thier roles in transmembrane voltage/ action potentials Ok, in other words.. the ions are too small and not uniformly purposed/moving to have such any such disruptive effect from hindering the AP process. Thanks for the insight, if I could trouble you for a source you surely would receive the BEST answer and this would be a resolved question. |

Why isn't there any repulsive force between Na+ and K+ disrupting thier roles in transmembrane voltage/ action potentials The electrochemical gradients are estabished from movement and difference of each ion internal and external concentrations - K+intracell/K+extracell -, NOT between differing ions ie not between Na+ and K+. |

SPINAL CORD: Do the axons from white matter synapse with the cell bodies in grey matter? I am studying Excercise Physiology, for the purposes of personal training, from that vantage point I am trying to solidify a big picture understanding mostly. So no i don't have to know the nitty gritty of a particular tract, my texts and resources have illustrated the big differences between the white and grey matter and thier main functions but do not really address what if any signaling takes place between each other. I was guessing and take it from your answer they do. Is there a typical pattern or does each pathway feature a unique setup between the white and grey matter? |

Understanding Membrane / Resting Potential from the perspective of ions? For anyone else interested I found a voluminous, free, online resource with animations and very detailed explanations which addresses the topic here: st-andrews.ac.uk/~wjh/neurotut/mempot.html |
